To all whom it may concern:

Be it known that we, ALBERT DE LAsKI and P TER DUNoAN THROPP, citizens of the United States, and residents of Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Vehicle-Tire, of which the following is a specification.

Our invention relates to vehicle-tires, with the objectin view of providing a durable and efficient tire of pneumatic type which will not be liable to creep on the rim of the wheel.

Our invention more particularly contemplates a structure in which an anti-elongating strip is located along the interior of the wovenfabricbody of'the tire, either along-the interior of the inflatable, tube which is intended to. be inserted within the woven-fabric body a 'a view in transverse section, showing the parts as they appear when in use with the antielongating strip on the interior of the inflatable tube. Fig. 2 is a similar view showing the anti-elongating tube between the inner inflat able tube and the fabric body. Fig. 3 represents the manner of introducing the anti-elongating strip between the inner tube and the fabric body before the ends'of the fabric body are spliced. Fig. 4 is a view showing the tire split along the side for the purpose of introducing and removing the anti-elongating strip after the tire is completed. Fig. 5 is an enlarged view showing the means of inserting the anti-elongating strip within the inner inflatable tube before its ends are permanently united; and Fig. 6 is an enlarged view in detail of a portionof the anti-elongating strip opposite the valve for inflating the inner tube, showing a hole formed through the strip for the passage of the valve or for the admission of air, as the case may be. The wheel-rimis denoted by'l. It may be conveniently formed in two annular sections, as is common, for the purpose of introducing the tire into position with one of the sections of the rim in place and then applying the other and bolting themtogether.

The inner inflatable tube of the tire is denoted by 2, the fabric body by 3, the winding of the exterior of the fabric body by 4, and

I the outer rubber covering or tread by 5'.

The fabric body 3 is preferably a circular woven tubular fabric, and preferably has its ends left with the warp-threads extended, as shown at 6 and 7, Fig. 3, for the purpose of splicing the ends of the tube together to make an annular ring when the inner tube and the antielongating strip shall have been introduced, or the ends of the fabric body may be united in any other well-known or approved manner. 1

The anti-elongating strip is denoted by 8. It preferably consists of a band of steel having its inner face made convex to correspond to the inner wall of the tube, and it is intended to be made of such a length that when its ends are overlapped and unitedas, for example, riveted, as shown at 9, Fig. 5+its length will be such as to press the tire firmly to the exterior of the rim.

In assembling the parts of the tire in the manner shown in Fig. 1 the inner tube 2 is first inserted in the circular woven tubular fabric 3 and its ends left slightly apart, as shown in Fig. 5. The anti-elongating strip 8 is then inserted within the inner tube 2 and its ends united. The ends of the inner tube 2 are then made to telescope or overlap and are sealed air-tight. The ends 6 and 7 of the tubular. Woven fabric are then spliced, completing the annular woven ring exterior to the tube 2. The tube 2 is then inflated, distending the tubular woven fabric and forming a mandrel on which the winding 4:, either thread or tape,

together, the ends of the woven tube then spliced, the winding'applied, and the rubber tread being applied as before. The introduction of the anti-elongating strip Within the circular Woven tubular-body serves to bind it, as well as all of the parts exterior to the rim,

, and when introduced within the inner inflat able tube serves to bind it, as wellas the other parts, to the rim. This anti-elongating strip instead of being introduced into the unspliced ends of the tube may be introduced through an opening 10 formed in the side of the tire, Which opening may also serve for the introduction of the inner tube 2, as Well as the antielongating strip, and thus provide for the reneWal of either the tube or anti-elongating strip Whenever occasion may require Without disturbing the other parts of the tire save only.

along the opening 10, Which is in a position to be covered by a flange of the rim.

What We claim is- 1. A tire consisting of a circular Woven tubular fabric having its ends suitably secured together, threads applied to the exterior of the circular Woven tubular fabric, a tread exterior to the threads, an interior inflatable tube and an anti-elongating strip within the circular Woven tubular fabric.

2. A wheel-tire including a circular tubular fabric, an inflatable tube located within the tubular fabric and an anti-elongating strip located Within the inflatable tube.

In testimony that We claim the foregoing as our invention we have signed our names, in presence of two Witnesses, this 8th day of June, 1903.
